tailieunhanh - Lecture Medical assisting: Administrative and clinical procedures with anatomy and physiology (4/e) – Chapter 53

Diagnostic radiology has evolved immensely since the discovery of the simple x-ray beam. It has become a valuable screening and clinical diagnosis tool for physicians. In this chapter, you will learn the basics of noninvasive and invasive radiology as well as your role as a medical assistant in this testing. | 53 X-rays and Diagnostic Radiology 53- Learning Outcomes Explain how x-rays are used for diagnostic and therapeutic purposes. Compare invasive and noninvasive diagnostic procedures. Carry out the medical assistant’s role in x-ray and diagnostic radiology testing. 53- Learning Outcomes (cont.) Demonstrate the medical assistant’s duties when preparing a patient for an x-ray. Explain the risks and safety precautions associated with radiology work. Describe proper procedures for filing and maintaining x-ray films and records. 53- Introduction Diagnostic radiology is a valuable tool Screening Clinical diagnosis Medical assistant Role in noninvasive and invasive procedures Safety issues Proper handling and storage of films Preparation and instruction of patients 53- Brief History of the X-Ray Discovered in 1895 by Wilhelm Konrad Roentgen Electromagnetic wave Travels 186,000 miles/sec Short wavelength Penetrates solid objects . | 53 X-rays and Diagnostic Radiology 53- Learning Outcomes Explain how x-rays are used for diagnostic and therapeutic purposes.

Diagnostic and therapeutic uses Radiologist Physician Interprets films Radiologic technologists 53- Diagnostic Radiology Contrast medium Purpose Makes internal organs denser Blocks passage of x-rays to film Provides a clearer image of organs and tissues Types Gases Heavy metal salts Iodine compounds 53- Diagnostic Radiology (cont.) Invasive procedures A catheter, wire, or other testing device is inserted into a blood vessel or organ by a radiologist Requires surgical aseptic techniques Patients must be closely monitored, especially if anesthesia is used 53- Diagnostic Radiology (cont.) Noninvasive procedures View internal structures Standard x-rays Ultrasonography Do not require inserting devices, breaking the skin, or as great a degree of monitoring as invasive procedures Uses the conventional x-ray machine or specialized instruments 53- Apply Your Knowledge What is the difference
